Is there a maximum memory size limit for the SD flash?

Will the M4 support 16GB SD flash memory?

Hi,

Sorry I messed the SD definitions up, there should be even bigger cards supported by the hardware.

It is not directly stated in the documentation, but in the PDL documentation to the SDHC interface you will find the following:

Supports Standard capacity (SDSC), High capacity (SDHC) and Extended capacity (SDXC) memory

     SD standard - Up to 2GB SD memory card using FAT 12 and 16 file systems

     SDHC standard - over 2GB-32GB SDHC memory card using FAT32 file system

     SDXC standard - over 32GB-2TB SDXC memory card using exFAT file system

from: Capacity (SD/SDHC/SDXC/SDUC) - SD Association

Hello,

In case of PSoC 62 the maximum memory size limit for SD Flash is 128 MB.

Please refer to the SMIF section (Chapter 26) of the Architecture TRM for more details on this: https://www.cypress.com/file/399201/download

Thanks for the clarification and the source - i read all through that but i suppose I just missed it and 'ctrl-f' failed me.

Thanks again!
